ecalder, you may need a new PS pump. and air bubbles aren't as hard to get out as people make them out to be.

Really old thread revival, but wanted to make mention this graphic helped me solve my no heat problem.

I thought it was a clogged heater core, but after pulling this valve, I discovered it was the culprit.

On this topic, can anyone tell me if the bypass valve should trickle or flow freely? When I was testing its flow with water, it dribbled out, a little heavier than droplets, but not completely free like I would imagine.

Oh my goodness...this thread...so so good. That diagram may very well just save me wrestling out an old heater core and valve under the dash. I have the updated lawsuit valve in my iS, and don't have heat at all- ever. Good work OP!

I have the same problem and I think this thread just got my wife back into the vert.
